The BNZ Series Welding Liner is a critical consumable in MIG/MAG welding torches, designed to provide smooth wire feeding, reduced resistance, and enhanced arc stability. A welding liner serves as the pathway for the welding wire from the feeder through to the contact tip, making it one of the most essential components for maintaining consistent welding performance and minimizing downtime.
Tesco Metalcraft’s BNZ Series Liners are manufactured with precision and high-quality materials to ensure long service life and superior reliability, even in demanding industrial environments.
Series: BNZ
Material Options: Steel, brass-coated steel, PTFE (for aluminum wires)
Length: Available in multiple standard sizes (commonly 3m, 4m, and 5m depending on torch)
Wire Compatibility: 0.8mm – 1.6mm wire diameters (varies with liner type)
Torch Compatibility: Suitable for BNZ Series MIG welding torches and equivalent models
BNZ Series Welding Liners are widely used across industries, including:
Automotive workshops – body repair, chassis welding, and custom fabrication.
Shipbuilding and offshore applications – continuous duty welding in high-demand environments.
Heavy fabrication – structural steel, construction, and machinery production.
General manufacturing and repair workshops – ensuring consistent, efficient welds.
Their primary role is to guide the wire smoothly from the feeder to the contact tip, reducing drag, preventing blockages, and helping welders achieve flawless, uninterrupted welding results.
The BNZ Series Welding Liner is made from high-grade steel wire with a smooth inner surface. Depending on application, liners may also feature brass-coated interiors or PTFE (Teflon) coatings for specialized wire types (e.g., aluminum).
Steel liners → ideal for mild steel and stainless steel wires.
Brass-coated liners → reduce friction and extend liner life.
PTFE liners → perfect for soft wires like aluminum or flux-cored wires.
Smooth wire feeding → ensures stable arc and reduces spatter.
Durable steel construction → resists wear and tear in heavy-duty use.
Reduced friction → extends contact tip life and minimizes wire jams.
Versatility → suitable for steel, stainless, and soft wires depending on variant.
Easy replacement → designed for quick installation and maintenance.
Improved welding efficiency → consistent feed reduces downtime and boosts productivity.
BNZ Series Welding Liners are built for longevity and dependable performance. Precision manufacturing ensures tight tolerances and smooth bore surfaces, reducing wear on both the wire and the contact tip. They are tested under rigorous industrial welding conditions to guarantee consistent quality.
Fits BNZ Series MIG torches.
Compatible with a wide range of wire materials including steel, stainless, and aluminum.
